Tcd lets you set a working directory for a specific tab. Great if you've
got a session open and are editing some file in another location on the
filesystem, and decide you need to open more files in that directory.
This plugin works particularly well in combination with NERD_Tree.vim

Changes the current working directory, but only in your current tab.
When you enter this tab, the specified path will become your current
working directory. Saves the real current working directory, so when you
exit this tab, you will return to your prior location.

Known Issues

1. The "old cwd" (the one you switch to when leaving the tab in which you
called :Tcd) is set the first time you call :Tcd. This means that if
change your working directory later with the built-in :cd command, this
new location will be ignored when leaving :Tcd tabs.

Workaround: Don't use :cd if you are still using :Tcd tabs. Instead,
call :Tcd in other tabs. I don't expect there to be a real fix for this
unless Vim adds some autocommand that is run whenever the current
working directory changes.
